-LRB- CNN -RRB- -- Meg Ryan and John Mellencamp have ended their relationship after three years of dating , a report says .

The two split `` a couple of weeks ago , '' one of Mellencamp 's friends told Closer Weekly , which was the first to report the news .

The pair had kept their relationship relatively quiet . The couple began going out sometime in late 2010 , according to People magazine , after Mellencamp separated from his wife of 18 years , Elaine Irwin Mellencamp .

Ryan , 52 , and Mellencamp , 62 , kept time on both the East Coast and in Mellencamp 's longtime home of Indiana .

`` It was the distance , '' a source told People of the split . `` She lives in New York and he resides in Indiana . It was the long distance that ultimately was the cause . ''

Mellencamp 's friend had a different take .

`` I do n't think he loved all the attention he got just from dating an actress , '' the friend told Closer Weekly . `` I bet he 'll stay away from dating another famous person for a while . ''

Ryan , who has n't appeared in a movie since 2009 's `` Serious Moonlight , '' is currently directing `` Ithaca , '' a version of William Saroyan 's novel `` The Human Comedy . ''

Mellencamp 's new album , `` Plain Spoken , '' is due for release next month .
